sAW HANDLE.

Application led October 21, 1925. Serial No. 637,831.

This invention relates to handles for long woodmens saws, such asfelling and crosscut saw, and has for its objectto provide a removablehandle which is cheap to make, simple in construction, easy to apply,and'iirm in use; Whichis so proportioned and shaped that the workingforce applied thereto 'will .be transmitted to thesaw inthe mostadvantageous position and direction whereby the operation of the sawwill be rendered very much easier than in the usual handles now in use;whereby the saw will cut evenly and equally on both the pushing andpulling strokes, with less `expenditure of energy whereby the speed ofcutting is materially increased whereby the Wear of the saw is moreevenly distributed along the entire working length ofthe blade; andwhereby the balance of feel of the saw is greatly improved, therebyenabling the user y to perform his work with greater ease. The handle isalso so proportioned and shaped that the hands of the operator are-'wellremoved from the saw teeth and from the fastening nut thereby preventingthe accidental abrasion of his knuckles, as is commonly the condition inusing the handle-sat rpresent on' Similar numerals of reference refer tosimilar partsthroughout the several views.

Referring to the drawings my improved saw handle comprises a metalthimble 1, having a vertical axis, and holding a strong verticalwooden'handle piece 2 therein, adaptedl to be gripped by yboth hands ofthe operator, in the usual way. A. longitudinal shank 3 leads from thecenter' of the thimble 1, being cast integraltherewith, ina horizontaldirection and is about two inches long. This shank terminates in aVertical extenson comprising the end piece 4, and this portion may beabout one-andahalf inches long, or slightly longer, and it in turn endsin a horizontal extension con'iprising the back Vpiece 5. The said parts3, 4 and A5 form thus a single member vin which the parts 3 and 5 areparallel but oii'set one from the other, and adapted to engage thebackrand end of the saw blade 6 in the angle betweenthe parts 4 and 5.The surfaces of the said parts 4 and 5, which thus engage the endcornerof the saw, aregrooved by a triangular' or rather V-shaped groove7, lying substantially in the central plane therof and adapted toreceivethe end redges of the saw 6 to prevent the saw Vfrom any side motion inthe handle. The Vj unction` of the two portions of the groove Tisprovided with asmall cavity -8 at the corner, thus permitting the cornerof the saw to enter therein andvpermitting the f two parts 4 and 5 tobedrawn into close and :tight contactwith the end edges of the saw`without interference with the'l corner thereof.

vbolt 10 passes toholdjthehandleon the saw and to 'clamp itthereon.l Y

`This bolt 10 has a split` shank adapted to lie on each side of the sawblade 6 and through which the usual pin 11 passes, whereby it is securedto the saw blade. The bolt 10 passes thence upward, at a rearwardinclined angle, through the boss 9. A deep washer 12 is placed over thebolt 10, above the boss 9, and a leather washer' 13 is placed above thewaslier 12. A thumbnut 14 screws down on the bolt 10 and engages thewasher 13 and draws the handle on to the saw at a forward-downwardangle, thus insuring perfect contact between the back and end edges ofthe saw blade and ythe sides of the groove 7 in both the parts 4 and 5of the handle.

It will be observed that the shank 3 comes well down the saw blade andthis is the most practical position thereof since it brings thedirection and position of the force applied to the handle by the lowerhand (the upper hand is used mostly for. steadying the saw in such longsaws) in line with the cutting portion of the teeth' of the saw at thepoint of contact of said teeth with the log, thus'causing all said forceto be applied parallel with and in line with the cutting action and; not

wasting it by bearing down on the cutting' teeth, as is the effect ofthe usual saw handle. This fact also permits the same force on thepulling stroke to be effective in 'cutting the wood, instead ofvinakingthe pulling stroke practically an idle stroke as in the usualconstruction of saw handles.V Thus both strokes of the saw utilized totheir best advantage for cutting the wood, and 'in neither of them isany of the applied force wasted in moving lll out of contact with thehand.

the saw uselessly or in forcing the saw down into the log.

It will be observed that the parts 8, l and 5, which are formed in asingle integral piece, have all their outer or eXposed edges and cornerswell rounded so that the operator may grasp the back of the saw or themetal fitting at any point without danger of @hating or abrading hishand, especially as the washer 12 is deep enough to raise the thumb nutFurther, it will be seen in igs. 1 and 3 that the upper Surface of theboss 9'is inclined in a rearwarddownward direction, or substantially ati right-angles to the direction in which the bolty l() lies.

Having therefore described iny invention7 what I claiin is Thecombination with a saw blade having ya substantially rectangularrear-upper corner and an opening spaced therefrom in a diagonaldirection; of a Zshaped metallic onepiece structure having threeconsecutive parts, the two end parts lying in vertically displacedplanes and joined by the vertical central part, the central part and theupperforward part of said structure being provided With coplanarV-shaped grooves adapted to receive the said rear-upper corner of saidsaw blade, the said upper-forward part oi' said structure having alrearwardly inclined opening therethrough, positioned vertically over thesaw blade and directed towards said opening in vthe saw blade in adownward-forward inclined direction, the upper surface of said partbeing inclined in a p lane at right angles to the incline of saidopening, the lower-rearward part of said structure extending rearwardfrom the lower end of said vertical central part at a pointSubstantially midway between the cutting edge of the saw teeth and theback thereof, and terminating in a vertical socket; a vertical handlerigidly secured in said socket; a split bolt spanning said saw blade andpassing through said inclined opening in said upper-'forward part ofsaid structure; a pin passing through the tines of said syplitbolt andthreugh the opening in said saw; and a nut on said split bolt andengaging said inclined surface on the upper side of said upper-forwardpart o'l said structure, whereby said saw blade is drawn upward into thegroove in the upperforward part and rearward into the groove ofthecentral vertical part.
